But why must John thus go before Christ with a witness of deeds preaching Him? First; that we might hence learn Christ’s dignity, that He also, as the Father has, has prophets, in the words of Zacharias, “And thou, Child, shalt be called the Prophet of the Highest.” [Luke 1:76]
Secondly; That the Jews might have no cause for offence; as He declared, “John came neither eating nor drinking, and they say, He hath a devil. The Son of Man came eating and drinking, and they say, Behold a gluttonous man.” [Luke 7:33-34]
It needeth moreover that the things concerning Christ should be told by some other first, and not by Himself; or what would the Jews have said, who after the witness of John made complaint, “Thou bearest witness of thyself, thy witness is not true.” [John 8:!3]
